TRAILS - Tools for Real Time Assessment of Information Literacy Skills www.trails-9.org from the website - "TRAILS is a knowledge assessment with multiple-choice questions targeting a variety of information literacy skills based on 3rd, 6th, 9th, and 12th grade standards. This Web-based system was developed to provide an easily accessible and flexible tool for school librarians and teachers to identify strengths and weaknesses in the information-seeking skills of their students. There is no charge for using TRAILS." I have used this for several years, on and off, and found it very helpful in informing my instruction. The pre and post test structure of the tool makes it easy to see what you need to emphasize and what you have already been successful at teaching.
